Problems solved by technology

At present, some breakthroughs have been made in the construction of urban river landscape in my country, but some of them are only for flood control and trade purposes, one-sidedly emphasize the function of water conservancy and ignore the ecological landscape effect of the river, some rivers adopt hard slope protection, a

Embodiment 1

[0011] Embodiment 1 Ecological Restoration Method of Recycled Water Landscape River Polluted Water Body

[0012] The total length of the river is 20km, the width of the upper mouth of the river is 6m~50m, and the width of the bottom is 4~45m. The area of ​​the formed water body is about 400,000 m2. The section of the river is very narrow, that is, 5-6m. It is not single, and does not occupy the land area. It can regulate and store the river water, and it can also give people a refreshing and pleasing visual effect. It has become a beautiful landscape in Tianjin Airport Processing Zone. In addition, a circular shallow bay is set at a certain distance in the ecological river, which adds beauty to the river and plays a certain role in flood control and drainage. Reeds are planted on both sides, reeds with a width of about 3m and a height of 2m, water onion and other plants, and a 10-15m plant belt is set on the river bank. Compared with the river channel of Weijin Road in Tianjin...

Abstract

The invention relates to an ecological restoration method for polluted water of a regenerated water landscape river, in particular to a method for restoring polluted water of a landscape river by adopting methods of ecological bank protection, vertical greening, setting of a bottomland and an ecological wetland and the like. The chemical oxygen demand (CODcr), biological oxygen demand (BOD5), N and P content of the water of the river restored by adopting the method are greatly reduced. The river bed is stabilized, the ecology is improved and the environment is beautified by taking the engineering measures that ecological bank protection of a compound section is adopted, the dike is protected in a mode of selecting a natural soil bank slope and a natural gentle slope and planting trees and grass, and timber piles, wooden frames and rubble stones are adopted at the steep slope of the river bank. A vertical ecological series consisting of land plants, emergent aquatic plants, floating plants and submerged plants is sequentially arranged from the bank to the water center to adsorb nitrogen and phosphorus and enrich heavy metals, the vertical ecological series provides a perching and living space for microbes and aquatic animals, and the diversity of river species is increased. The set bottomland can prevent degradation, reduce pollution, store nitrogen and fix nitrogen. Three plants, namely reed, acorus calamus and canna, are planted in the artificial wetland to remove N, P and CODcr.

Description

technical field [0001] The present invention relates to an ecological restoration method for polluted water bodies of landscape rivers with reclaimed water, in particular to a method for repairing polluted water bodies of landscape rivers by means of ecological revetment, vertical greening, setting up beaches and ecological wetlands, and adopting the method to restore BOD in water 5 , CODcr and N, P content decreased significantly. Background technique [0002] The development of urban rivers is always changing due to the development of society and cities, and the restoration of urban rivers is an eternal subject. As a result of industrialization and urbanization in today's society, there is an unprecedented crisis in the living environment. The various functions of the city have produced many diseases, and the urban river has not been spared, so that the river has once become a corner that the city avoids. The development of society and the construction of ecologically liv...
